A tweet from Johan Andersson from this past summer offers a revelation not noted here at the time, as the tweet seems to confirm rumors from 2007 that the Frostbite 2.0 engine that will power the upcoming Battlefield 3 will not support Windows XP, saying: "Frostbite 2 is primarily developed for DX11. XP & DX9 is _not_ supported, 64-bit OS is recommended. Lots of time to upgrade if you haven't!" The thread about this on the Electronic Arts Forums also has comments noting this was revealed already, and there are slides in DICE's SIGGRAPH 2010 presentation indicating Frostbite 2.0 will only support DirectX 10 and DirectX 11.

Frankly, most people that are still running XP on thei gaming machines don't have new enough hardware to play BF3. Cetainly none of my PC gaming friends that I play with regularly nor serious gamers (the ones that BUY games, not those still playing Counter-Strike) run XP. Huge kudos to DICE!
